Description
Technical field
The present invention relates to control the apparatus and method of wind turbine driftage.
Background technique
The driftage process is used to wind turbine, rotates certain driftage angle to allow cabin and its rotation blade, obtains best wind direction with relative blade.Blade rotates around horizontal axis of rotation, and this axis normal is in plane of rotation, and plane of rotation is limited by rotation blade.
So-called " driftage angular error " is the angle between horizontal axis of rotation and the actual wind direction.
In order to obtain the maximum capacity of wind turbine, the spin axis of blade should be parallel to wind direction.In this case, when this parallel axes during in wind direction, the driftage angular error is 0 ° of value.
The spin axis of rotation blade also has vertical angle of inclination, and this angle of inclination is used to prevent rotation blade contact tower under high wind speed.So the spin axis of blade leaves parallel direction-this influence in fact slightly and is left in the basket in following consideration.
During the driftage process, rotate around vertical yaw axes in the cabin of wind turbine, is parallel to wind direction-except possible vertical angle of inclination up to the spin axis of blade.The yaw axes usually vertical axis with the tower of wind turbine is consistent.
The driftage process is carried out by electric power or hydraulic pressure installation usually.So-called " control of driftage driver element " uses wind direction to measure.These measurements are undertaken by one or more sensors, and this sensor is usually located on the cabin of wind turbine.
When rotation blade placed the upwind of tower, if wind transducer is positioned on the cabin, sensor did not expose with free way.So they do not measure wind direction, the not interference that produces by rotation blade.
Alternatively, wind also may be owing to this process is twisted through rotation blade.When wind through out-of-date, may be in addition around the cabin hastening phenomenon itself.This distortion is wind speed normally, turbulent flow, the function of wind direction and vertical wind deflection.
So during the driftage process, the blade spin axis is associated with uncertainty with aliging of wind direction.
At low wind speed and middle wind speed, the output of the power of turbo machine is responsive to suitable driftage alignment.It has been generally acknowledged that on wind turbine the relation between driftage alignment and the power output is a cosine square function, rather than simple cosine function.This high sensitive reason relates to the leeward wake flow behavior of wind turbine.
If the cosine square relation is that effectively 5 ° driftage angular error will be corresponding to cos
2The power output of (5 °)=0.99.This will mean that 1% output power is lost.Such a loss sounds it being unessential, but it becomes more than the annual 100.000kWh easily for larger wind turbines.
In addition, the driftage angular error has produced the higher dynamic load that acts on the wind turbine structure, and this is undesired phenomenon.A large amount of fatigue loads on the turbo machine relate to the driftage angular error.
Up to the present, suitably the go off course suitable calibration of the wind transducer that alignment problem installed by the cabin solves.At the model test period of wind turbine, the driftage alignment is measured by the contrast of yaw direction and wind direction.This measurement is carried out at the meteorological bar of free-standing place.Any skew can be by wind transducer the permanent alignment of mounting bracket be adjusted.Any dependence to wind speed can be adjusted by carry out suitable correct algorithm in driftage driver element controller.
But some difficulties occur in this conventional method.At first, conventional method is to the limit sensitivity in the used base measurement.They are to the calibration sensitivity of instrument, and this instrument is installed in the meteorological bar of free-standing place, is used to measure wind direction.
They are to the calibration sensitivity of yaw direction, and this direction is measured at test turbo machine place, also the accuracy sensitivity of the test turbo machine carriage of the wind transducer that the cabin is installed.
In addition, the accuracy of driftage will be the function of the installation accuracy of individual wind turbine upper sensor in related domain always.
In addition, the distortion of the stream in related domain may be different from the stream distortion in the test turbo machine.For example, this is produced by the difference in the engine room facilities, and this difference may influence the accelerating performance on the cabin, and may influence the difference in the ambient flow condition.
Usually, because the aviation beacon, the difference in the engine room facilities may take place.Difference in the ambient flow condition for example can be turbulent flow or stream deflection, for example owing to the reason of the topographic feature of turbine positions.
Summary of the invention

This passage comprises measuring device, and this measuring device is arranged to the parameter of measuring by the air-flow of passage.Measuring device is connected with controller, and this controller is arranged to the parameter of surveying of using air-flow, direction of the wind comes from detection and the driftage angular error between the spin axis, and this driftage angular error is used to adjust the driftage angle in cabin.
In a preferred embodiment, the wind comes from through before the rotor plane, wind is conducted through opening and inlet passage as air-flow.
If the direction of the wind comes from is not parallel to each other mutually with the spin axis of rotation blade, environment be the wind comes from and had horizontal component in rotor plane.This is the situation that the driftage angular error takes place.Horizontal component is need be measured to change the component of driftage angle in passage.
If the driftage angular error exists, the horizontal component of the wind comes from or its at least a portion are passed through the opening inlet passage of passage in a looping fashion.This brings circuit air-flow in the passage, and this air-flow is measured according to the present invention.
This causes change institute's survey cycle of air-flow, and this variation is the function of driftage angular error, so this is used for driftage control purpose.
The direction of driftage is the direction that cycle variation in time can be reduced, and wherein spin axis need be adjusted on this direction.This direction is by determining with respect to the azimuthal changes phase of rotor plane.Direction and spin axis are parallel to each other if environment be the wind comes from, and during the rotor period of rotation, the cycle of air stream changes and to be reduced to being seen in time minimum value in the passage, or even are reduced to " 0 ".
This means that spin axis is rotated by the driftage angle, reach minimum value or even disappearance up to the cycle variation of measuring.The cabin may be maintained at this position then, and changing again up to the cycle increases.
Increase if change, rotor plane or cabin are rotated again, become minimum or disappearance up to variation.
During the period of rotation of rotor, the driftage of wind turbine advantageously is performed based on variation measuring period of measuring device.
This inventive device provides the very simple and accurate method of driftage control.
This creationary method convection current distortion is insensitive, and measures the driftage angular error in important place, i.e. driftage angular error in the rotor plane zone.
The advantage of the creative method of this driftage control is its maximization energy output, and the dynamic load on the wind turbine structure is faded to minimum.So the life-span of wind turbine components is extended.
In a preferred embodiment, passage extends on outward direction from rotor axis as follows with radial manner: the longitudinal axis of passage is basically parallel to the longitudinal axis of rotor blade.
Like this, passage can be positioned at the rotor blade place.The opening of passage is positioned at the specified distance from rotor axis.
Like this, may be based on the driftage of in rotor plane, controlling turbo machine from the measurement of rotor axis a distance.Passage be rotor blade integrated component within the scope of the invention.
In a preferred embodiment of this invention, measuring device is arranged to the speed of measuring air-flow in the passage and/or air.
In a preferred embodiment of this invention, air-flow is measured by ultrasonic sensor.
The speed of air-flow and/or air will change during the period of rotation of rotor in the passage, and by should change with rotor-position relatively, may determine that direction that wind turbine should be gone off course is to reduce the driftage angular error.
Like this, also may use air-flow in the passage or air velocity the time become and measure with the estimated yaw angular error and control the driftage in wind turbine cabin.
In a preferred embodiment, passage is disposed in the wheel hub, and wherein passage passes through wheel hub as follows: opening is disposed in the wheel hub and faces one another.They are orientated as and are basically perpendicular to rotor axis.Like this, measure and to be performed, this means to measure to be performed and not from the turbulent flow of rotation blade or minimum turbulent flow is only arranged in the rotor front.
With respect to prior art system (described in background), this is great improvement, because wind direction is measured influence and the interference that does not have from the rotor rotation blade.
In addition, measuring device location and being protected in the passage of leeward side of direct weather effect.With being positioned at the top, cabin is direct wind also thus upward, the sun, and the windage scale of the target of rain and snow is compared with blade, and this is great improvement.
Because the present invention, may be with the diameter or the cross section of following method selector channel and opening thereof: they enough greatly (for example in the scope of 40mm) to avoid the passage inner salt, the deposition of earth or snow.
Ice in access portal place and passage gathers also and is avoided by suitable cross section.
In another embodiment, the part that is used as measuring device through the propulsion device or the impeller of out-of-date rotation when air.This angle of rake spin axis is perpendicular to the longitudinal axis of passage.Under the situation of yaw error, the air-flow rotary blade in the passage is to rotate on certain orientation.Because the rotor rotation, propulsion device rotates in an alternating manner.
In another embodiment, measuring device is arranged to the cycle differentiation of measuring air pressure in the passage.Like this, during the rotation of rotation blade, the variation of passage internal air pressure is used to estimate the driftage angular error of cabin driftage control.
According to the present invention, measuring device is arranged to the direction of air-flow in the sense channel.This can be obtained by the valve that is arranged in the passage.Encoder is used to read the position of valve.Valve is opened by the air flows in the passage in a looping fashion and/or closes.
Therefore the position by reading valve may sense channel in the direction of air-flow, may determine the angular error of going off course by measuring to compare subsequently with the position of rotor.
In a preferred embodiment, compare the position of airflow direction and rotation blade, with the direction of estimating to the wind comes from respect to the rotor plane environment.
Like this, may use the detection of airflow direction in the passage, with the driftage angle of control wind turbine blade, even luffing angle.
The mechanical resistance of valve is changed in a preferred embodiment, to avoid the excessive opening and closing of valve.So the excessive control behavior of wind turbine is avoided.
In a preferred embodiment, the opening of passage tilts between 0 ° and 90 ° with respect to rotor plane, is not orthogonal to the wind component of rotor plane with seizure.
For example, passage in the end by slight curvature, so that catch wind from rotor-side.
Like this, opening is arranged in increases the cycle variation of measuring under the driftage angle error condition.
Air-flow will be increased on a rotor-position of wind at opening, and be reduced on opening is changed to relative position away from wind.During the rotation of rotor, when ambient wind when being parallel to each other substantially with rotor axis, the cycle of wind speed component changes and to be minimum or to disappear that this is owing to be independent of the identical air quantity of rotor-position just at inlet passage in the rotor plane.
But, under driftage angle error condition, because the rotation of rotor is measured alternately.In embodiments of the present invention, measuring device the time become to measure by integration or similar fashion in time by evaluation.
Therefore may be by measuring, amplitude, driftage angle sum of errors/or the driftage of control wind turbine is determined in the skew of root-mean-square value or the like.
For example, when rotor plane be aligned be basically perpendicular to ambient wind to the time, integral value is greater than or less than " 0 ".This value indication need not to change the driftage in cabin.
This inventive device is textural at it to be very simple, so even also allow accurate the measurement under the rigorous environment condition.
In improving mode of execution, each blade of wind turbine is assigned to a passage, so for three blades, number is that three passage is used, and each passage is used to measure inner wind direction.

Embodiment
Fig. 1 schematically illustrates driftage angle error alpha about wind turbine WT with top view, the relation between the direction of the direction IW that the wind comes from and the horizontal component HCIW that the wind comes from, and this wind turbine comprises cabin NA, the rotor R of wheel hub HB and band blade.Cabin NA can rotate certain driftage angle around so-called first axle FA, and this first axle is the vertical axis of tower T.The rotation blade of rotor defines rotor plane RP.
If driftage angle error alpha takes place, the IW that the wind comes from is not parallel to the spin axis RA of rotor R.This causes the loss of output power and causes acting on higher wind load on the wind turbine components.
Driftage angle error alpha is reduced by rotating spin axis RA with respect to the direction of the IW that the wind comes from.
Fig. 2 shown when the driftage angular error when being minimum value " 0 " according to wind turbine WT of the present invention, with reference to figure 1, this means that the spin axis RA of rotor R is aligned in the direction of the IW that the wind comes from.
The cabin NA of wind turbine WT is connected with wheel hub H, and that wheel hub H is installed as is rotatable and carry three blades around spin axis RA, and this paper is not shown.
Cabin NA is installed on the tower T in rotatable mode, so it can rotate certain yaw angle around the axis FA of tower.
Wheel hub H is full of channel C H.Channel C H comprises measuring device MD, and this device is used to measure the airflow direction through channel C H.This air-flow is produced by component HCIW, and this component is caught from the wind comes from by the opening of channel C H.
As shown here, driftage angle error alpha is near " 0 ", so the horizontal component of being caught by channel C H is also near " 0 ".
Wind turbine WT comprises computing unit CU, and this unit is the direction of surveying of air-flow among the integration channel C H in time, as shown in Figure 3.
Computing unit CU is connected with control unit ContU, and this control unit uses the driftage angle of integral value with control and correction cabin NA.
Fig. 3 has shown the horizontal component HCIW that surveys of the air-flow in the channel C H, referring to Fig. 2.
In this case, the direction of air-flow will replace between first direction and second direction in the channel C H.Should alternately will take place in constant mode more or less, have the approaching constant amplitude of alternating direction.
If the time distortion shape of the component HCIW that surveys is integrated in time, be the result near the value of " 0 ".So driftage angle error alpha also equals the value of " 0 ".
Fig. 4 shown when driftage angle error alpha is certain value according to wind turbine WT of the present invention, in this case, and about 45 ° of this angles with respect to rotor plane.
So the rotor axis RA of rotor R is not aligned in the direction of the IW that the wind comes from.
The passage that is full of wheel hub H is caught the horizontal component HCIW of the IW that the wind comes from.So this component HCIW causes the air-flow in the passage, this air-flow is measured according to the present invention.
Fig. 5 has shown the horizontal component HCIW that surveys of air-flow in the channel C H, referring to Fig. 4.
In this case, the direction of air-flow will replace between first direction and second direction in the channel C H.Should alternately will take place in constant mode more or less, show the approaching constant amplitude of alternating direction.
If the time distortion shape of the component HCIW that surveys is integrated in time, will produce value greater than " 0 ".So the driftage angle in cabin need be adjusted.
